I’m early into my powerlifting journey and preparing for what will likely come as I progress with heavy deads! Wearing these for the first time this week though, what I love about them is they do not move!!! No rolling downwards, no readjusting. They just stay put. Amazing! I’ll be wearing nothing else in future.

Finally a g string that can support my frustrating leaks when sprinting! Others haven’t held up and double undies are my saviour. Thank you so much xxx

Sad I only have one pair, need to order more asap! Will let all my members know about how good these are too 🙌

Wife loves them. Feel and support is what she like most about her thong.

The best period/leakproof undies in the game!
I've tried a few different brands, and these ones are the best by far - comfortable, practically invisible under tights, and very absorbent.
I also love the little waterproof bag that comes with them, so you can change them when needed (ie: in the middle of a comp) and know they're hygienically tucked away until you can get them into the wash. I've got so much more confidence when doing double unders or heavy OH lifts.
Yes, they're a little more expensive than other brands, but they are more than worth the extra $.

I have been wearing liners everyday for the last 15 years as I have always suffered from having weak pelvic floor muscles. I am only 28 and haven’t had kids yet so I have always been worried. What’s to come after that. I met with the beautiful ladies from Double undies at the fitness expo and introduce me to their incredible product which I have now tried for the first time and is an absolute game changer time to throw out those liners and not look back! I have seen ads online with a similar concept but the features that double undies offers in their product is unmatched. It’s definitely worth the buy. The quality is insane and the comfort throughout the day was a great experience.

These undies are great, they keep me dry when I exercise!

Does their job well, comfy and great for protecting against leaks and absorbing sweat during workouts. Generous sizing next time I will get a size down.

Absolutely love my Double Undies. Ordered one pair for strength training and have now ordered a second pair. Just so good to know that you have that little bit of security when lifting heavy.

These have been a life saver in the gym. Lifting running and hyrox I always leak and get sick of wearing pads. I love these are in a g string so i can wear them with no undie lines will definitely be buying more thank you.

Honestly, I’m not a G wearer as I feel like I’m constantly picking them out of the lady garden, that my labia aren’t made for the tiny strip most Gs have but I was desperate to try a “seamless” flesh coloured pant I could run and jump and do activities in without showing my VPL to the world. I’ve been using other undies for my “LBL” but have found them bulky and nanny like and was looking for a “something” I could wear under a very tight dress and not worry about leaking on the DFloor.
At first I thought WTF when I saw the shape, but I’m fair so I thought oh well, I’ve paid top dollar so I’d better try. It took a hot minute to get used to the extra “undercarriage” coverage but holy Oprah…. I don’t feel like I’m stuffing my self back into a tiny belt and I’m not picking my pants out of my butt. These are SO SO comfy and no VPL and I can attest that not only do they provide great coverage but also great butt view but NO VPL! I’ll definitely be purchasing again! I’d give these 100/10!!!!

Comfortable to wear while being discreet and giving you security. Will definitely be investing in more

I wore them for my powerlifting competition over the weekend and they gave me that extra confidence I needed when stepping onto the platform. Comfortable, supportive and stayed exactly where they needed to — no distractions, just focus on the lifts! 💪🏼🔥

Feeling strong, confident and competition-ready. Highly recommend Double Undies! 🏋🏼‍♀️✨

Great quality, would recommend to anyone!

As someone who trains hard and lifts heavy, these have honestly been a game changer! I never have to stress about leaks during workouts anymore, and I can wear whatever colour leggings I want with complete confidence.

They’re so comfortable, stay in place, and actually do what they promise. I wish I’d found them sooner! Every active wāhine needs these in her gym bag.

Thank you, Double Undies, for creating such an amazing product. I’m obsessed and will never train without them again! 🫶🏼💪🏼💕

Ordered one pair to trial. Comfortable. Will be ordering more

I feel way more comfortable running now. I nearly gave it up all together before I found Double Undies!!

I have to say, when I opened the pack, I wasn't sure if these were going to work for me....but after wearing them walking, running, lifting weights, gardening and even an impromptu swim, I'm completely converted! They don't move AT ALL (even when leggings slip), so comfy, and do exactly what they're supposed to do. Great product!
I'm usually a NZ size 10 (occasionally 12) and went for size M, which seems to be perfect.
Customer service is outstanding, cannot recommend highly enough. I'll definitely be buying more.

Brought these for running and tried them for the first time during my first Hyrox. They are great, comfortable and work. I want to get another pair.

Not only seamfree but no leaks or odour (especially on leg day when it's most needed)! The only undies I can confidently wear at the gym!

Ordered one pair to trial. They definitely live up to the hype, and I will be ordering more. Love them

I use the double undies briefs for my long runs and they keep me dry and no chaffing so win win for the undies. I will definitely be buying some more.

I have used the brief and the thong, they both work- gives you confidence. would recommend.

From my very first interaction, I felt like I was supporting a real person and a grassroots business rather than just another online store. The customer service is genuinely second to none.

The G-string itself is surprisingly comfortable. It’s completely invisible under tights and, best of all, gives me so much confidence during workouts. I’m no longer worrying about leaks or rushing to the bathroom before every session—I can just focus on training.

For sizing, I initially ordered a medium because that’s what I wear in tights, but I found the small fit me much better and was even more comfortable. When I contacted the team to exchange the two unworn pairs from my 3-pack, they went above and beyond and organised FedEx shipping so I had them in time for my competition. That level of service is rare.

Standard postage is a little slower, but with customer service like this, it’s a trade-off I’m more than happy to make.

I’m already planning to order the beige pair next… and maybe even branch out into lighter-coloured tights now too!

Love these, so comfortable. No more stressing about leaks at the gym.
